XPS 15 9570, problem limited processor

Good morning
I have a dell XPS 15 9570 with an i7-8750h, but it is stuck at 0.8ghz and 38%.
It seems that Dell used an integrated controller that blocks the processor, which means that mine is stuck at 17w instead of 45w.
I updated the bios, but it doesn't change anything.
You can see the problem on the screenshot.
Does anyone know what to do to resolve this problem?

Go into Setup (F2 at powerup).  Is the AC adapter correctly identified with its power rating, or showing unknown?
